- Citation practices can vary significantly from one field to another. For example, articles in biochemistry often contain over 50 cited references, while a typical mathematical paper has perhaps only 10. SNIP is an advanced citation indicator that corrects for such differences - in other words it normalises for subject differences.
- SNIP - Source Normalized Impact per Paper.
- Measures contextual citation impact by ‘normalising’ citation values.
- Takes a research field’s citation frequency into account.
- Considers immediacy - how quickly a paper is likely to have an impact in a given field.
- Accounts for how well the field is covered by the underlying database.
- Calculates without use of a journal’s subject classification to avoid delimitation.
- Counters any potential for editorial manipulation.
- Both SNIP and SJR are integrated into the Scopus Journal Analyzer. This allows you to select up to 10 journals. Five comparative graphical representations of the journals are available: by SJR, SNIP, Citations (count), Documents (articles count) and % Not Cited.
